Engadget: Much of this stuff was shown off publicly for the first time at CES last week, but we thought it might be interesting to get everything that wireless charging company Powermat has planned for 2011 into one convenient place -- and that's exactly what this here slide deck has done for us. The first products in the pipeline for this year include a charging case for the Nokia N8, targeted for early Q2, along with a two-device portable charging mat that includes a built-in battery (7,800mAh!) that promises up to four full smartphone charges while staying completely off the grid; look for those to run $40 and $130, respectively.
